A very good question. My iPad 1 still runs on 5.1.1 and the only reason I paid full price for this a few days ago is be cause the AppStore says requires 5.1 Or above. I am having nightmares with this. I am getting virtually every patch with unusable distortion and regardless which way up the screen is, the keyboard doesnt function. There seem to be no fixes for any of this on this site. I am so tempted to go back to the AppStore and give 1 star and vent my anger. So far this has been an utter waste of money.

Lol this thread makes about as much sense as asking why wont my PC with a intel 386 CPU run Windows 8. I mean really you wouldn't go out and buy a DVD to try and play in your VCR and then complain because it doesn't work. The CPU in the ipad 1 is just too slow to handle such complex DSP tasks nothing short of upgrading is going to help you.
